RULE.

Specification of Letters Patent.

Patented Dec. 13, 1910.

Application filed October 2, 1909. Serial No. 520,626.

To all whom 'it 'ma'y concern:

Be it known that I, DAVID ELMER Wears, a citizen of the United States, and a resident of Olympia, in the county of Thurston and State of Washington, have invented a new and Improved Rule, of which the following is a full, clear, and exact description.

This invention relates to rules which constitute combined squares, levels and bevels, and relates more particularly to a combination tool of this class which comprises a body, an arm having a pivotalconnection with the body, means for clamping the arm in a plurality of angular positions'relative to the body, and means for indicating the relative angularity of the body and the arm. The body if so desired, may be provided with a level.

The object of the invention is to provide a simple, strong and durable rule which can be used as a linear or other measuring device, which can-be employed as a square, or as abevel for determining angular1t1es,and whlch can be folded into small and compact form.

The invention consists in the construction and,ombination of parts to be more fully described hereinafter and partlcularly set forth in the claims.

Reference is to be had to the accompany ing drawings forming a part of this specification, in which simi ar characters of reference indicate corresponding parts in all the views, and-in which a Y Flgure 1 1s a side elevation of an embodiment of.my invention showing certain of the parts in dotted outline; Fig. 2 is a plan view of the rule showing the same folded,

Fig: 3 is a side elevation of the rule showing the parts extended; and Fig. 4 is a side elevation of a detail showing t e level removed from the body of the rule.

- Referring more particularly to the draw ings I provide a' rule bod 10 fashioned from'wood or other suitab e material and having indicated thereon graduations' 11. It will be understood that the rule body may be of any suitable length and may be graduatedin accordance ,with individual preference and special conditions, though I prefer to make the body six inches long and to have it graduated in inches and their fractional parts. The body has associated therewith a part comprising spaced sides 12 and a back 13 therebetween, the back having at oneextremity an end extension 14. The sides may consist of metal lates or the like and are extended at one en beyond the body, the extending member being rounded, as is shown most clearl in Figs. 1 and 3.

An arm 15 is pivota ly mounted between the projecting ends of the sides, by means of a suitable pin 16 having 'a threaded laterally projecting end upon which is mounted a clamping wing nut 17. The latter serves to clamp the arm in any desired angular position with respect to the body. The proends of the sides have graduations.

shoulder 20 which a uts against the end 21 of the'back 13 to limit the extension of the.

arm and to insure the alinement'of the arm "and the body when the arm is fully extended. The arm has a longitudinal recess 22 in which are located'rule extensions 23. The first of these is pivotally mounted within the arm by means of a pin 24 and has a shoulder 25 ada ted to abut against a .cor-

responding sho der 26 at the free end of the arm to limit its extension. /1

The suc cessive rule sections are pivotally associated by means of pivot pins or rivets 27. The sections'are provided with suitable 'graduations 28 and may be of'hny suitable number. I have shown for exam 1e, three sections, each four inches long, 5 that the total extended length of this type of rule is two feet. v

The arm has a notch 29 for the insertion of a finger-nail to permit its,m'anipulation,

and the body has a corrigponding edge recess 30 which ,permits t e notch 29 to be reached. 4

The body, at the side "remote from the arm is recessed to receive a level. This 'level comprises a level-glass or tube 31 of 'any suitable transparent material and bent at right angles. It ,is mounted upon a su tab e glass carrier ,by meansyof eyes 33 integral with the carrier to receive one of the glass arms. At the end, the carrier has a scale 34: inwhich the other arm of the glass rests. The carrier is pivoted upon a plate 35 by means of a suitable rivet or the will be understood that by providing a level glass bentat right angles as shown, a single glass can be used for leveling the rule in two directions, the bubble traveling from one arm of the glass to theother. The plate has sight openings'39 and 4:0 whichpermitthebubble to be viewed. It is secured upon the body by means of screws or pins ll or in anyother suitable manner.

The carrier has an extension finger 42 having an opening to receive an adjusting pin 4:3 The latter'has a screw-head 4a located in an opening of the laterally disposed edge 37 and carries a helical spring 45, and

"at the side of the finger remote from the spring, a nut 46. It will be seen that by ,turning the screw in one direction or the 30' other, the carrier can be adjusted pivotally to regulate the level. a

The body at the end adjacent to the clamping nut has a curved bevel or cutaway part 47 to permit the manipulation of the clamp ing nut. The arm has an edge recess 48 so that the rule extensions can be easily extended when folded within the arm.

Having thus described my invention, 1

claim as new, and desire to secure by Letters Patent 1. In a rule, a body having a recess, a

plate covering said-recess, a carrier pivototally associated therewith, means for clamping said arm in a .plurality of positions, means for indicating the relative angularity of said body and said arm,.means for leveling the rule, said body being recessed to receive said arm when the rule is folded, said arm having a recess, and successive pivotally-connected rule extensions, the first of said extensions being movably associated with said arm whereby said extensions are adapted to be folded into said recess of said arm, one only of said extensions being secured to said arm.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
